Where's My Product?

back

Here are some samples of how you might fetch data for a single product across three related events in each framework. Each example assumes that the model is the same and that information for the individual Product is returned as a bean from an Application.ProductService object via a getProduct() method that accepts one productid argument. The affected code is highlighted in each example:

<cffunction name="needProduct">
	<cfargument name="event" required="true" />
	<cfset var rc = event.getCollection() /> 
	<cfparam name="rc.productid" default="" /> 
	<cfset rc.product = Application.ProductService.getProduct(rc.productid) />
</cffunction>

<cffunction name="productDetail"> 
	<cfargument name="event" required="true" /> 
	<cfset needProduct(event) />
	<cfset event.setView("product/detail") /> 
</cffunction> 

<cffunction name="productEdit">
	<cfargument name="event" required="true" /> 
	<cfset needProduct(event) />
	<cfset event.setView("product/form") /> 
</cffunction>

<cffunction name="productSave">
	<cfargument name="event" required="true" />
	<cfset var rc = event.getCollection() /> 
	<cfset needProduct(event) />
	... save the product ... 
	<cfset setNextEvent("Handler.Event"[,"query_string=parameters"]) />
</cffunction>

<fuseaction name="getProduct" /> 
	<set name="attributes.productid" value="" overwrite="false" /> 
	<set name="product" value="#application.ProductService.getProduct(attributes.productid)#" /> 
</fuseaction>

<fuseaction name="productDetail">
	<do action="storeModel.getProduct" />
	<do action="storeView.productAdmin" /> 
</fuseaction>

<fuseaction name="productEdit">
	<do action="storeModel.getProduct" />
	<do action="storeView.productEdit" /> 
</fuseaction>

<fuseaction name="productSave">
	<do action="storeModel.getProduct" />
	<do action="storeView.productSave" /> 
</fuseaction>
